A new study found that trans-vaccenic acid affected immune development in mice, while human samples showed related links that need more research.
A new national analysis finds U.S. adults are using more supplements, with growing interest in products marketed for immune, gut, skin, joint and inflammation-related health.
An Australian study found egg allergy prevalence declined after infant feeding guidance changed, adding real-world support to recommendations that parents should not unnecessarily delay common allergens.
The study does not prove that one drink can reduce disease risk, but it offers a useful look at how researchers test functional food claims in people.
A new observational study in remote Amazonian Indigenous communities found that gut microbial diversity changed after medical visits, but the findings do not mean lifesaving treatment should be avoided.
A new review finds alcohol contributes to a wide range of diseases and injuries, but some risks may fall when people reduce or stop drinking.
A major genetics study suggests body weight can shape gut bacteria, but researchers say your microbiome alone does not determine whether you develop digestive disease.
A randomized trial found many peanut-allergic toddlers could tolerate more peanut exposure after carefully monitored oral immunotherapy, but experts stress this is not a treatment parents should try on their own.
A new lab study suggests cranberry juice compounds may help certain antibiotics work better against some UTI-causing bacteria, but researchers say human benefits remain unproven.
New research in humans and mice suggests eating may create a short-term metabolic state that can shape T cell readiness, though the findings do not mean specific meals or eating patterns directly “boost” immunity.
A new clinical study suggests an experimental treatment may help reduce some harmful effects of accidental gluten exposure, though it is not a cure.
A lab study suggests a non-heat treatment can change peanut proteins, but it’s far from making peanuts safe for people with allergies.
New research shows how compounds in breast milk support a delicate microbial balance, including bacteria often seen as harmful.
A small human study finds that while gluten can pass through saliva, the amount is typically low and easy to reduce.
Early lab research suggests certain high-fat diets could disrupt key protective cells in the gut within days, though the findings come primarily from animal models.
A new study finds that sleep patterns and diet both influence immune function, but through separate biological pathways tied to inflammation and long-term health.
New research suggests some people may not be able to fully use dietary fiber without the right gut microbes.
A new study finds that cooking methods like microwaving, baking and air frying can significantly affect how well your body can access key nutrients in foods like carrots and tomatoes.
A small human study suggests vitamin D supplementation may affect how the immune system interacts with gut bacteria in people with inflammatory bowel disease.
A mouse study suggests fiber in whole wheat foods may support gut health by triggering anti-inflammatory responses through the microbiome.
A global modeling study finds that adding vitamins and minerals to staple foods like salt and flour already reduces nutrient shortfalls at scale, with potential to expand impact at low cost.
A randomized clinical trial found high-dose vitamin D supplements did not reduce COVID hospitalizations or symptom severity, though researchers observed a small signal suggesting fewer long COVID symptoms among participants who took the vitamin.
New research shows specialized immune cells actively train the body to tolerate common foods such as corn, wheat and soy, offering clues that could one day help prevent food allergies.
A scientific review finds the popular supplement does not work like GLP-1 drugs and that its metabolic effects appear to depend heavily on the gut microbiome.
Researchers analyzing nearly 15,000 adults found that some antibiotics were linked to changes in the gut microbiome four to eight years after treatment.
